The tenfold increase in speed for the analytics (GC, HPLC, and SFC [supercritical fluid chromatography], all with MS) over the last decade has shifted the choke point in many workflows from analytics ... read more

The moisture absorbing polymer consumable
described in this article is designed to remove moisture from wet samples inline during extraction as well as from the post-extraction solvent extract. read more

With the ongoing globalization of the world’s food supply, the presence of potential contaminants in food is an ever-important and increasing global safety concern. Developing accurate and reliable ... read more

Various species of methacrylates are widely used in dentistry as filling materials. These consist mainly of an organic matrix, based on a monomer system of methacrylates and inorganic additives. read more

The above headline is not a typo, since there is no “k” in “hydraulic fracturing.” This correction was just one of many misconceptions addressed in a daylong session on hydraulic stimulation of petro-... read more

Charge transfer chemical ionization (CI) was among the ionization types studied decades ago by researchers investigating fundamental Characteristics of chemical ionization. However, the technique was ... read more

In recent months, the growing shortage of helium has gained national attention and raised concerns of availability and cost among users. Laboratories in particular rely on helium for analytical ... read more

The first commercial liquid chromatograph was probably an amino acid analyzer. These ion exchange chromatographs were so specialized that they had almost no impact on chemical analysis outside of ... read more

Samples that contain large amounts of sediment or particulates are difficult to extract using U.S. EPA Method 3535 (SPE, solid-phase extraction). While a standard 47-mm SPE disk is able to process a ... read more

The last decade has seen increased interest worldwide in alternative fuels. Although biodiesels are still a minor part of the liquid biofuels transportation market, biodiesel
consumption is ... read more

Since its beginnings over half a century ago, the Eastern Analytical Symposium has been “the” place to become energized about the latest developments in analytical technology and methodology. read more

For gas chromatography (GC), the big news at Pittcon® 2012 was the absence of Agilent and PerkinElmer. This was a consequence of an overall downsizing caused by the “six-year effect” where the cycles ... read more

Chromatographs are everywhere; many analytical labs may now contain more such instruments than analytical balances.
Indeed, gas chromatographs and liquid
chromatographs are used to solve separation ... read more
